Part Information Review and Datasheet Update

flux

Done — I reviewed the part, found the official datasheet, updated the project metadata, and cross-checked the current terminals and footprint against the datasheet workflow for part projects

What I fixed
  • Corrected the MPN from SW1_1-2_3-4 to PTS645SL43SMTR92 LFS
  • Added the official datasheet URL
  • Filled in missing manufacturer/package metadata
  • Set all four terminals to Passive
  • Added pin descriptions:
    • 1: Switch terminal A
    • 2: Switch terminal A
    • 3: Switch terminal B
    • 4: Switch terminal B
Mismatches / concerns
  • No clear symbol or pin-number mismatch found
  • No clear footprint identity mismatch found — the footprint asset name and 4-pad numbering are consistent with the datasheet
  • Remaining uncertainty: I can confirm pad count and numbering, but the searchable PCB data does not expose full land-pattern dimensions, so I cannot conclusively verify every pad size/spacing value against the datasheet’s recommended layout
  • Minor modeling note: the project prefix is SW, while individual terminal elements still carry terminal-style internal prefixing; that is not a datasheet mismatch
If you want, I can do one more pass focused only on the footprint geometry and compare the pad layout dimensions against the datasheet drawing in more detail.
